[c-nsp] IPv6 BGP on 7200

[Church, Chuck]

What if you manually added 915 to the trunk to 9/1, or disable spanning
tree for 915, assuming you're using PVST (and it's loop-free :)?  Can
you look at the stats for 9/1, to see if it's taking any errors or
dropping anything from the RSM?  Is it possible that the 5.5(13) you've
been using forever didn't have an issue with older IOS on the RSM, but
does in fact have an issue with newer stuff?  Are the logging levels
sufficiently high enough on the sup?  If you debug the CAM table, do you
see entries come and go in VLAN 915?

Hi,

Assumed that at first, but even after removing 4 unused VLANs, no change
in behaviour.  (I've searched for about a *week* for "normal" issues,
like "too many VLANs", "spanning-tree doing weird things", "VLAN not
configured on all trunks involved", etc.)

Especially given the fact that it *works* with a RSFC in the very same
cat5k and *does not* work with a RSM in the same switch leads me to the
conclusion "the switches involved are not to blame".

Something ancient but very proven, 5.5(13).

No.  (When removing the VLAN on the RSM side, the Sup side will display
"removing from trunk" messages, but otherwise, everything seems to be 
"as ever")


The thing that I really want to know is "why is 'show trunk' displaying
the VLAN in question as 'not active'"...

(debug c5ipc on the RSM side didn't yield any interesting news either)
